The invention provides a preparation method of 3-hydrazino-5-morpholinomethyl-2-oxazolidinone, and belongs to the technical field of chemical synthesis. The preparation method comprises the followingsteps: carrying out a cyclization reaction on 1-Boc protective hydrazine-3-morpholine-2-propanol and a carbonic ester substance to obtain 3-Boc protective hydrazine-5-morpholinomethyl-2-oxazolidinone;and finally hydrolyzing to obtain the AMOZ. The chemical structural formula of the 1-Boc protective hydrazine-3-morpholine-2-propanol is shown in the specification, the chemical structural formula ofthe 3-Boc protective hydrazine-5-morpholinomethyl-2-oxazolidinone is shown in the specification, and the chemical structural formula of the AMOZ is shown in the specification; and the carbonic estersubstance contains at least one of diethyl carbonate, dimethyl carbonate, di-tert-butyl decarbonate, and dipropyl carbonate. The method is simple in synthetic route, the AMOZ is synthesized by adopting a one-pot method, and the catalyst is used in the preparation process, so that the loss in the synthesis process is greatly reduced, the synthesis yield and the recovery rate are relatively high; and the method is suitable for mass production.

A cyclizative atmospheric CO2 fixation by unsaturated amines such as allyl and propargyl amines under mild reaction conditions, efficiently leading to cyclic carbamates bearing a iodomethyl group, have been developed utilizing tert-butyl hypoiodite (t-BuOI).
